• Product Description

    The FLIR DM166 is the most affordable multimeter with built-in thermal imaging – a must-have tool for commercial electricians, automation, electronics, and HVAC technicians.

    Featuring Infrared Guided Measurement (IGM™) powered by an 80 x 60 FLIR thermal imager, the DM166 visually guides you to the precise location of temperature anomalies and potential problems faster, more safely, and efficiently.

    The feature-packed multimeter is an ideal tool for troubleshooting and diagnosing complex issues in both high-voltage and low-voltage applications.



    One tool gets the job done

    Quickly scan for overheating components with IGM

    Diagnose faults with broad DMM test functions

    Troubleshoot easier with the unique combination of onboard thermal imaging and traditional DMM test functions 


    Identify energized and potentially faulty equipment from a safe distance

    Safely check for live connections using non-contact temperature measurement

    Carefully measure voltage with integrated non-contact voltage detection

    Work with peace of mind knowing your meter has a CAT III-600V, CAT IV-300V safety rating


    Rich feature set covers both high-voltage and low-voltage applications

    Reliably take 600 V AC/DC voltage measurements and 10 A AC/

    DC current measurements

    Remove high-frequency noise that affects readings with the Variable Frequency

    Drive (VFD) measurement function

    Precisely measure resistance up to 60 MΩ, frequency up to 50 KHz, and capacitance up to 10,000 µF
